摘要：

A novel second-order cascaded Delta-Sigma modulator concept is presented. The first integrator is extracted, and implemented by an FM oscillator. The result is a simple, extended multibit Delta-Sigma modulator with no component matching restrictions, and a high sampling frequency potential. Without the oscillator, the modulator becomes a second-order Delta-Sigma F/D converter.
